Abstract

An eccentric wheel and a driving body which are in deflection transmission connection are arranged in a pump body of the electric diaphragm pump, the eccentric wheel is connected with an output shaft of a motor, the driving body is connected with a main diaphragm, and an outlet one-way valve diaphragm is arranged between a pump cover and a diaphragm cover; wherein in the pump body, the diaphragm frame, the main diaphragm diaphragm, the inlet one-way valve diaphragm, the diaphragm cover and the pump cover which are stacked in sequence, the outer edge part of one member is provided with a plurality of mounting columns which are uniformly distributed in the circumferential direction and axially extend; the outer edge parts of other components are respectively and correspondingly provided with axially-through mounting parts for inserting the mounting columns, and are configured as follows: the mounting columns and the mounting parts form a circumferential limiting pair, and the end parts, extending out of the pump cover and / or the pump body, of the outwards-extending ends of the mounting columns are provided with locking parts; and the locking part is welded and fixed with the pump cover and / or the pump body. And the bearing strength of the component is effectively improved through structural optimization.

Description

technical field [0001] The invention relates to the technical field of fluid transportation, in particular to an electric diaphragm pump. Background technique [0002] Due to its compact structure, small size and light weight, diaphragm pumps are widely used in many fluid transportation fields, especially in beverage equipment such as water dispensers and coffee machines. A typical electric diaphragm pump, the lower part of the pump body is directly sleeved on the outer periphery of the motor, and the upper part of the pump body and the pump cover are fastened by the protrusions to achieve locking and fixing between the components; obviously, limited by its own structure, this solution The non-circumferential pump body and the pump cover are buckled and locked, which directly affects the strength of the components in the use state that requires pressure. SUMMARY OF THE INVENTION [0003] In order to solve the above technical problems, the present invention provides an ele...
